AMVAEndFrameInfo structure (amva.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The AMVAEndFrameInfo structure contains information for the IAMVideoAccelerator::EndFrame method.

Syntax

typedef struct _tag_AMVAEndFrameInfo {
  DWORD  dwSizeMiscData;
  LPVOID pMiscData;
} AMVAEndFrameInfo, *LPAMVAEndFrameInfo;

Members

dwSizeMiscData

Size, in bytes, of the buffer that pMiscData points to. The value must be 2.

pMiscData

Pointer to a buffer that contains data for the video accelerator.

This buffer must contain a WORD value equal to the same surface index that passed to the corresponding IAMVideoAccelerator::BeginFrame method.

Remarks

The buffer pointed to by pMiscData cannot contain pointer values, because their addresses will not be valid in kernel mode, where frame processing occurs.
